I need a MATLAB CODE for richardson's extrapolation please;
specifically question 1C below. Thank you!
1. Apply the extrapolation process described in Example 1 to determine N3(h), an approximation to f'(xo), for the following functions and step sizes. f(x) = ln x, Xo = 1.0, h = 0.4 f(x) = 2* sin x, Xo = 1.05, h = 0.4 a. A
